Antarctic ice melting faster than ever, studies show

The Guardian / Matthew Taylor / 13 June 2018

Ice in the Antarctic is melting at a record-breaking rate and the subsequent sea rises could have catastrophic consequences for cities around the world, according to two new studies.

A report led by scientists in the UK and US found the rate of melting from the Antarctic ice sheet has accelerated threefold in the last five years and is now vanishing faster than at any previously recorded time.

A separate study warns that unless urgent action is taken in the next decade the melting ice could contribute more than 25cm to a total global sea level rise of more than a metre by 2070. This could lead eventually to the collapse of the entire west Antarctic ice sheet, and around 3.5m of sea-level rise.

April 2018 was third warmest April on record

NASA Global Climate Change / 16 May 2018

In spite of the low temperatures in parts of the United States last month, 2018 experienced globally the third warmest April in 138 years of modern record-keeping, according to a monthly analysis of global temperatures by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York.

Last month was +0.86 °C warmer than the average April of the 1951-1980 period; this value is in line with the 1.8 °C/century rate of increase of the past 40 years. Only April 2016 (+1.07 °C) and April 2017 (+0.92 °C) were warmer than the past month, and April 2010 (+0.84 °C) was only insignificantly cooler than this year’s April.

Avoiding self-inflicted extinction. What are the solutions?

News24 / Robert J Traydon / 01 June 2018

Humankind has the unenviable duty to address the looming threats of runaway climate change and environmental collapse. At risk are Earth’s millions of species and our human civilisation, all of which could face severe hardship or even extinction by the end of this century.

It seems like an impossibility: to meaningfully reduce our impact while thriving on fossil-fuelled technology and unrestricted population growth. But, there are solutions that could not only slow the rate of climate change and ecological decline, but also reverse them to pre-industrial norms.

Many will regard the solutions that follow as crazy, but keep in mind they’re an order of magnitude less crazy than the sacrifices people will be forced to make if our planet’s biosphere fails.

Changes in global water supply hint at future conflicts, crises

Globe and Mail / Ivan Semeniuk / 16 May 2018

By combining 14 years’ worth of satellite data, scientists have captured a startling portrait of the world’s water supply undergoing rapid transformation. The new analysis points to areas where there is increasing potential for conflict as a growing demand for water collides with the impacts of climate change. In Canada, the maps shows shifting water supplies that include wetter, more flood-prone regions in many areas of the country but a general drying out in the western sub-Arctic.

“This is an eye-opener,” said Roy Brouwer, an economist and executive director of the University of Waterloo’s Water Institute who was not involved in the analysis. “It raises awareness that things are changing and that in some areas something has to happen to counter and anticipate some of the catastrophes that may be waiting for us in the not-so-far future.”

Nate Hagens asks: Where are we going?

Great Simplification / 30 April 2018

After gaining a Masters degree in Finance at U of Chicago and then 10 years of work as an investment banker on Wall Street, Nate Hagens had some insight that changed his life direction. His next step was a PhD in Natural Resources from U of Vermont. This is his 9th Earth Day talk.

Highest April temperature ever

Common Dreams / Andrea Germanos / 05 May 2018

Weather experts at the United Nations just said that the highest April temperature ever may have just been recorded—an ominous sign that comes on the heels of the monthly average concentration of carbon dioxide in the atmosphere hitting the highest level on the books.

Speaking to press at the UN headquarters in Geneva, Clare Nullis from the World Meteorological Organization (WMO) referenced the extreme heat in the Pakistani city of Nawabshah, which reportedly reached 50.2°C (122.36°F) on Monday.

“This is April—it’s not June or July—it’s April,” Nullis said Friday. “We don’t normally see temperatures above 50 degrees C. In fact, as far as we’re aware, we’ve never seen a temperature of above 50 degrees C in April.”

The Transition Framework

The Transition Towns movement aims toward veering away from excessive consumption – to deal with the conjoined problems of peak oil and climate change – but also in the belief that we may create an essentially more contented society, through building strong and resilient local communities. We will get to know our neighbours better, because we shall all need one another in the time to come.
